Nitrous oxide or ‘laughing gas’ has been used as an anaesthetic since the mid-1800s. In this apparatus, nitrous oxide and oxygen are bubbled through the clear glass bottle separately so the right mix of air and anaesthetic can be achieved. The apparatus includes facemasks to allow patients to breathe in the gases, as well as tubing for nasal inhalation.
Intended for general surgical use in a hospital, the complete kit in its brown fibre box with carrying handle weighed 110 kg and cost 10 guineas in 1935. The apparatus was made by Allen & Hanburys Ltd and the nitrous oxide cylinders by Coxeter. The apparatus was expensive to buy and maintain and had to be used by trained staff.
